On the other hand, the motion detection unit 40 is installed at one end of the spindle 15 to detect when it is close to the one end of the inner case 16, the second detection sensor 42, and one end of the inner case 16 It further includes a third detection sensor 43 that is installed on the side inner surface and senses when the spindle 15 comes close to the other end of the spindle 15. At this time, the second and third detection sensors 42 and 43 are electrically connected to the controller 20.

The second detection sensor 42 detects when one end of the spindle 15 and one end of the inner case 16 are close to each other, and transmits the detected value to the controller 20, as shown in FIG. 2. When the one end of the spindle 15 and one end of the inner case 16 are close together, the spindle 15 is retreating and the trunk door is closed due to this, but it is in a state that it is almost approaching the fully closed point in the trunk door opening section. .

The third detection sensor 43 detects when one end of the inner case 16 and the other end of the spindle 15 are close to each other, and transmits this detection value to the controller 20, as shown in FIG. When one end of the inner case 16 and the other end of the spindle 15 are close to each other, the spindle 15 is advancing and the trunk door is open due to this, but it is almost approaching the full opening point in the trunk door opening section. will be.

The term'completely open' means a state in which the trunk door is no longer open in the opening and closing section of the trunk door and reaches the maximum opening point, and the'completely closed' refers to the trunk door opening and closing section. It means a state in which the door is no longer closed and reaches the maximum closing point, that is, the point locked by the locking device.

Eventually, the motion detection unit 40 transmits the reached detection value to the controller 20 when reaching a point before the trunk door is fully opened or completely closed within the opening/closing section of the trunk door, and the controller 20 By receiving the detected value of the motion detection unit 40 and operating the electric clutch 14 while operating the motor unit 12, power is transmitted between the motor unit 12 and the screw 13, In the process of manually opening and closing the trunk door, even if the user continues to open and close the trunk door, the trunk door is fully opened and closed automatically at the end.

On the other hand, the electric trunk opening and closing device capable of manual opening and closing according to the present invention further includes a smart key detection unit 50 for detecting a smart key, wherein the smart key detection unit 50 is electrically connected to the controller 20 do.

After the smart key detection unit 50 detects the smart key, when the user opens and closes the trunk by using a button of the smart key, the controller 20 uses the motor unit 12 and the electronic clutch to automatically open and close the trunk door. 14).

If necessary, the controller 20 receiving detection values for various types of signals, such as a motion detection sensor or a camera recognition module, a user approach detection sensor within a distance, a user voice recognition sensor, and a vibration signal recognition sensor, You can also control automatic opening and closing.

In addition, when an obstacle inside or outside the trunk door occurs by adding a sensor for recognizing an obstacle when opening and closing the trunk door, the controller 20 may control the movement of the trunk door to be restricted.
